In order to solve the problems, the utility model adopts the following technical scheme.

The utility model provides a take pile tip mud jacking pipe bored concrete pile steel reinforcement cage structure, includes single strand reinforcing bar, stranded reinforcing bar, single strand reinforcing bar, stranded reinforcing bar inner are fixed with interior ring bar, stranded reinforcing bar outer end is fixed with outer ring bar, inboard fixed surface is fixed with the mud jacking pipe between interior ring bar and the outer ring bar, adopts stranded reinforcing bar to tie up fixedly, can form the skeleton the same with mud jacking pipe and sounding pipe diameter, can the centre gripping tie up and fix including, outer ring bar department inboard surface, structural support power is big, improves the fastness of whole steel reinforcement cage.

Furthermore, the multi-strand steel bars are stacked together by adopting four groups of steel bars and are fixed by steel wire bundling.

Further, the single-strand steel bars are uniformly distributed on the outer surface of the inner ring steel bar.

Further, the multi-strand steel bars are uniformly distributed and fixed on the inner side surfaces of the inner ring steel bars and the outer ring steel bars.

Further, a sound tube is fixed on the inner side surface between the inner ring rib and the outer ring rib.

Further, the outer ring ribs are uniformly distributed and fixed on the outer surfaces of the multi-strand steel bars from top to bottom.

Further, the inner ring ribs are uniformly distributed and fixed on the inner side surfaces of the multi-strand steel bars and the single-strand steel bars from top to bottom.

Compared with the prior art, the utility model has the advantages that:

(1) The multi-strand steel bars are adopted for binding and fixing, a framework with the same diameter as that of the grouting pipe and the sounding pipe can be formed, the inner side surfaces of the inner ring and the outer ring steel bars can be clamped and bound and fixed, the structural supporting force is large, and the firmness of the whole steel bar cage is improved.
